' Application filed March 15, 1884. (No model.)

To all whom, it may concern Be it known that I, HUGH I. OAVANAUGH, a citizen of the United States of America, residing at Adrian, in the countyof Bates and State of Missouri, have invented certain new and useful Improvements in Bolting-Reels for Flour-Mills; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification. I

My invention relates to reels for bolting flour and other ground grain; and it consists in the improvements hereinafter fully described and set forth, and then sought to be specifically defined and pointed out in the claims.

In the accompanying drawings, forming a part of this specification, Figure 1 is a side view of a bolting-reel constructed in accordance with myinvention, part of the sievecloth being removed. Fig; 2 is a transverse section on the dottedline, Fig. 1. Figs. 3 and 4 are detailed views; and Fig. 5 is a detail sectional view of a portion of the reel,

- illustrating the arrangement of gasket or pack ingtherein.

On the shaft A, at suitable distances apart, are rigidly mounted a series of spider-wheels,

B, provided peripherallywith several lugs,

a, perforated and threaded for the passage of exteriorly-threaded spindles b. Each spindle b has rigidly keyed thereon a ratchet-wheel, c. A leaf-plate, d, is also-mounted on each of said spindles 1), adjacent to the ratchet-wheel 0 thereof, and carries near each extremity a gravity-pawl, cl, designedto engage the teeth of the ratchet. A rod, D, extends longitudinally through the screen, and is secured to the 1 rods. The outer extremity of each spindle bis reduced to form a tenon suitable for entering an opening therefor formed in a bearingplate, 6, which rests against the inner face of a ring or annular bar,E, designed to form the outer skeleton portion of the reel.

The foregoing description applies more particularly to those parts which are located intermediately in the reel structure.

To provide for the extremities or end portions of the reel, I extend the central portion of one of the spider-wheels, so as to present a hub, F, secured to which are the inner ends, f, of a series of inclined rods, G, the outer ends of said rods being connected to the skeleton ring of the screen end adjacent thereto. The I bands, K K, the ends of each section K K being provided'with supplemental plates is is, having an ear, k perforated for the passage of a threaded bolt, L, which connects each adj acent pair of supplemental plates k k. Springs embracing the respective bolts, are interposed between the ears in and the bolt-head k of the said bolt, and between the said ears and the nuts k on said bolts.

To secure the desired adjustment the nut I is rotated on the threaded portion A of the shaft A, so that said nut would be caused to travel in either direction, thereby moving the ring E near to'or from the adjacent ring E, and thereby lengthening or decreasing the longitudinal dimensions of the structure. The sieve-cloth J is now placed exteriorly upon the various rings E E, so as to encompass the same and be held in position by means of the clamping-rings K K, the bolts is being rotated so as to cause the ears k adjacent of the supplemental sections, to approach each other, thereby contracting the said ring-sections'K K, and thus securely retaining the sieve-cloth in position. The springs k exert a pressure upon the bolt-heads k and nuts 70 to prevent the accidental rotation of the bolts k and the inadvertent loosening of the various parts. The outer parts are rigidly braced with respect to the shaft A in the following manner:

One series of pawls, d, of each pair of rods D are thrown out of engagement with the ratcl1- et-wheels 0, while the other series of pawls are moved into engagement with said ratchetwheels. The detailed view, Fig. 4, shows the relative position of one pair of pawls with regard to a single ratchet-wheel. Either of each pair of rods D may be moved longitudinally, which movement causes the pawls engaging with the ratchet to intermittently engage the successive teeth of the said ratchet-wheels and rotate the same, thereby causing the spindles b to travel radially in an outward direction in the threaded lugs a, and ultimately resulting in the said spindles rigidly forcing the plates 0 against the inner side of the rings E E, and thereby bracing said rings with regard to the spider-wheels l5 and shaft A. By reversing the positions of the various series of pawls the spindles can be retracted to their first position. In most instances it is desirable to interpose a flexible or elastic gasket or packing, z, between the rin 1G 1G and the several clamp-sections K K.

From the foregoing it will be apparent that a boltingreel embodying my improvements may be readily adjusted to secure any desired length of reel, and that by employing skeleton ringsE E of various diameters the transverse dimensions can be increased or decreased at will, the various devices and improvements coacting and contributing to secure such adjustments.

I claim 1. The combination, in a bolting-reel, of a supporting-frame comprising a series of rings,

a sieve-cloth encompassing said supportingframe, a series of ring-sections adapted to hold the said cloth onthe rings of the supporting-frame, devices for contracting and expanding said ringsections, and means 'forlocking said devices, as described, substantially as and for the purpose set forth.

2. The combination, in a bolting-reel, of a central shaft, one or more spider-wheels mounted thereon, and provided with a series of threaded lugs, a series of threaded spindles located in said nuts, devices for effecting the rotation of said spindles to secure their radial movement, and a series of sieve-supporting rings expanded and braced by said spindles, substantially as set forth.

3. The combination, in a bolting-reel constructed and operating as herein described, of a series of rings, a sieve-cloth encompassing the same, a series of adjustable spindles for braeing said rings, and devices for effecting the rotation of said spindles in series, substantially in the manner set forth, and for the purpose specified.

4. The combination, in a bolting-reel constructed and operating as herein described, of a series of rings, a sieve-cloth encompassing the same, a series of adj ustable spindles for bracin g said rings, a gear-wheel mounted on each of said spindles, and a series of rods provided with pawls for effecting the rotation of said gearwheels in either direction, substantially as set forth.

5. The combination, in a bolting'reel, of a central shaft, one or more rings supported thereon, a sieve-cloth encompassing the same, a series of ring-sections adapted to hold said sieve-cloth on the rings of the supportingframe, and a gasket or packing interposed between the rings and the ring-sections, substantiall y as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
